# AES for MIPS

# October 2010
#
# Code uses 1K[+256B] S-box and on single-issue core [such as R5000]
# spends ~68 cycles per byte processed with 128-bit key. This is ~16%
# faster than gcc-generated code, which is not very impressive. But
# recall that compressed S-box requires extra processing, namely
# additional rotations. Rotations are implemented with lwl/lwr pairs,
# which is normally used for loading unaligned data. Another cool
# thing about this module is its endian neutrality, which means that
# it processes data without ever changing byte order...

# September 2012
#
32 33 34 35
# Add MIPS32R2 (~10% less instructions) and SmartMIPS ASE (further
# ~25% less instructions) code. Note that there is no run-time switch,
# instead, code path is chosen upon pre-process time, pass -mips32r2
# or/and -msmartmips.

# There is a number of MIPS ABI in use, O32 and N32/64 are most
# widely used. Then there is a new contender: NUBI. It appears that if
# one picks the latter, it's possible to arrange code in ABI neutral
# manner. Therefore let's stick to NUBI register layout:
#
($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
#
# The return value is placed in $a0. Following coding rules facilitate
# interoperability:
#
# - never ever touch $tp, "thread pointer", former $gp;
# - copy return value to $t0, former $v0 [or to $a0 if you're adapting
#   old code];
# - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
#
# For reference here is register layout for N32/64 MIPS ABIs:
#
# ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
# ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
# ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
# ($gp,$sp,$fp,$ra)=map("\$$_",(28..31));
